Today my evo started idling weird at a light and continued to do so for the rest of the day. I have no idea what this could possibly be. I have an AME wide and gauge and when ever it started idling weird it also started running super lean. If anyone knows what's going on please help me haha thanks!

 

Sticky idle control valve on the throttle body? Vacuum leak from blowing off a hose? Had you just boosted hard?

 

does idle hunt up and down or just randomly go lean? any CELs?

check all vacuum lines.

 

Itve got the idle set to 900rpm and when it goes lean it drops to about 600-500 and then it might bounce up to running super rich for a second but then as soon as I drive it sits where it's supposed to on the wide band

 

I'd start with testing for vacuum leaks. That's cheapest and easiest.

Does it go lean while cruising?

 

No the only time it goes lean is when it has to idle for more than 10 seconds

 

do you have a way to datalog?

 

Having the same issue, check the EGR hose. That is a common source for strange idle. Check the IAC to make sure it moves fully.
